In classical singing, you're taught to serve up your vowels as if they're on a silver platter, to let your voice transport them as beautifully as you can ... But that's not the way people speak.

The great artists, the finest storytellers, really sing their consonants. Listen to Garth Brooks: He does it by communicating through well-shaped consonants, not by blaring his voice.
